Wherigo decompiler (for Windows)?

Question

Is there any LUA decompiler (for Windows, at best) that would work on Wherigo cartridges?

I've tried luadec, unluac.jar and some PHP script found in Internet, but the first both fail to recognize the format, and the last just makes infinite loop.

Answer 1

I was able to disassemble a cartridge using this script.

In my case the script returned four files with jpeg extension: one empty, two valid JPEG and one which turned out to be a compiled lua script. Using unluac.jar I decoded it to a readable script.
